The WOW121 is a universal sound decoder for locomotives with DCC-ready 21-pin MTC connectors, and can also be used with any of TCS' motherboards. The WOW121 requires a motherboard to interface with the locomotive. The motherboard will determine the support for the number of lighting functions as well as the type supported (LED or 12V/1.5V bulbs). A WOW121 decoder will support up to 8 lighting functions.


Note: Function 5 and 6 are not programmable, and will only output constant bright lights. Take this into account when wiring multiple lighting functions.
